Cursor is an AI-native 🏷️#code-editor built by Anysphere Inc., founded in 2022 by four MIT classmates — Sualeh Asif, Arvid Lunnemark, Aman Sanger, and Michael Truell. Forked from 📝VS Code, Cursor integrates AI autocomplete, chat, and autonomous agents directly into the editing experience. It reached $1B ARR and a $29.3B valuation by November 2025 — a 3x leap in six months — with 📝OpenAI attempting an acquisition before Anysphere chose to raise instead.
Cursor 3 is a complete redesign around managing fleets of autonomous coding agents. The shift is architectural: the primary workflow moves from editing code to directing, monitoring, and reviewing agents that handle implementation, testing, and deployment. Tab autocomplete runs on a Supermaven-derived engine with a 100K token context window. Multi-model support lets developers switch between GPT-5.4, Claude Opus 4.6, 📝Gemini, and proprietary models per task. Cloud agents execute CI/CD pipelines and test suites in sandboxed infrastructure without consuming local resources. Cursor also supports 📝MCP for connecting to external tools and context sources.
In the competitive landscape, Cursor occupies the IDE-native lane in a three-way split: Cursor (standalone AI IDE), 📝GitHub Copilot (multi-IDE extension), and 📝Claude Code (terminal-native agent). 📝OpenCode is the primary 🏷️#open-source alternative. Developer satisfaction tells a different story than revenue — Claude Code leads at 46% "most loved," Cursor at 19%, Copilot at 9%. The most common pattern among experienced developers is hybrid: Cursor or Copilot for daily editing, Claude Code for complex multi-file tasks.

For the longest time everybody raved about Cursor. Then I started using it — and then I started using Claude Code and 📝Codex directly in the terminal. I just lost interest entirely. The terminal-native workflow proved more powerful for how I actually build — multiple agents running in parallel, each with MCP access to 📝MythOS, no IDE layer between me and the work. Cursor solves a real problem for developers who think inside an editor. I don't anymore.
